1. A superabsorbent polymer composition comprising:
superabsorbent polymer particles comprising a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acid groups, wherein at least a part of the acid groups are neutralized; and
an antimicrobial agent,
wherein the antimicrobial agent includes a chelating agent including EDTA or an alkali metal salt thereof, a mixture of an organic acid and a silicate-based salt, and an agent for controlling a particle size of the antimicrobial agent,
wherein the organic acid is included in a content of 90 to 99.5 wt %, based on a total weight of the mixture of the organic acid and the silicate-based salt, and
wherein the mixture of the organic acid and the silicate-based salt is included in the content of 0.5 to 5 parts by weight, based on 100 parts by weight of the superabsorbent polymer particles.
